To on whom, it may concern:

- Be it known that I, ANTHONY J. SHAW, of

Bridgeton, in the county of Cumberland and State of New Jersey, haveinvented certain- Improvements in Glass-Blowing Machines, of which thefollowing is a specification.

This invention relates to certain improvements in machines for blowinbottles, jars, and analogous devices, as Wlll hereinafter fully a pear.

In tlie description of the said invention which follows reference ismade to the accompanying drawings, forming a part hereof, and in which-Figure 1 is an exteriorfront elevation of the improved machine. Fig. 2is an exterior side elevation. Fig. 3 is a section of Fig. 1, taken onthe dotted line 2 2 with certain parts thereof removed and Fig. 4 is afront view of .a part of the machine.

Referring now to the drawings, 1 is the base of the machine, provided,as is usual, with wheels for the purpose of its easy removal from laceto place. To the base 1 is secured the ed central column 2, to which isfastened the cam 3. This cam is best shown in Fig. 2, and it will beseen that it is provided with the inclined cam-face a and understoodthat there is a similar inclined face on the opposite side. The upperand lower horizontal cam-faces are denoted, respectively, by b and 4 isa table resting in camv 3 and ada ted to be rotated by hand about thefixed co umn 2 through the medium of the handles (1. Upon the rotarytable 4 are secured the bottlemolds 5, whichin Fig. 3 are shov as six innumber, These molds are commonly used in machines ofthis class, and eachone consists of a base 6, the hin ed members f, which are provided withhand es 9 for opening and closing the mold, a plate h, adapted to beslid by means of the handle '21 through a slot into the mold to form thebottom of the bottle or jar, and the locking devices and I thereforemake no claim to invention in the construction of the molds or thearrangement of the parts thereof relatively one with another. Inconnection with each mold, which is open at the bottom, is a plunger7,having a cavity in which a mass of molten glass is first made into aliollowbody. These lungers are alsocommonly in use, and in 't emselvesembody no part ofmy invention. No plunger is shown Fig. 2, for thereason that only one mold is illustrated in that figure and its plungeris within the mold. In Fig. 1 the lower portion of'one of these plungersappears to the left of the figure.

The stems whereby an up-and-down movement is directly communicated tothe plungers are represented by 9, and only one of these is shown inFig. 2, while two of them appear in Fi 1. The upper ends of the stems 9are t eaded,-as at 7c,'and screwed intothe lower ends of the plungers 7,so that a change in plungers to suit bottle-molds of difierent sizes maybe made Without disturbing the stems, and below the said threads thereare formed on the stems slotted en largements 10 for-the rece tion ofcertaino erating-levers 12, hereina ter described .T e lower ends of thestems 9 are internally threaded, and into them arescrewed the exeternally-threaded ends m, whereby the stems may be increased ordiminished in length to admit of a change in the depth of the plun er.This adjustment is made still more comp ete bythreading the anvil 13,(shown in-position only in Fi 2 and separately in'Fig. 4,) upon whicheac stem rests whilethe same is directly at the front of the machine,where the presser-man stands. The anvil is screwed 'lIltO the base 1.

Each one of the stems 9 is provided with a lever 12, before brieflyreferred to, which is fulcrumed to a pendent lug 16, and one end of thelever is slotted and enters the slot in the enlargement 10 of the stem,to which it is conne'cted by means of a pin 'n.- The other end of thelever carries a roller 17, which traverses the cam-faces of the cam, andthe form of the cam-face is such that as each mold in the ro tation ofthe table reaches the point at, Fig. 3,

the stem carrying its plunger. is suddenly raised to its highestposition within the mold and held thereat by the roller 17 traversingthe horizontal face c at the bottom of the cam until the mold approachesthe point ymrhere the stem and plunger fall to their lowest po sitionand remain thereat until the point x is again reached.

. mold when the same is closed, an 7 the end of The object of the anvili3 is to furnish positive support for each plunger during the pressingoperation, and to prevent the stems laterally striking the anvil as theycome to the front of the machine the head of the anvilis extended towardthe approaching stem and has its upper surface inclined, as shown inFig. 4, so that the end m will easily mount the anvil. v

The guides for the stems 9 consist of bored plates 19,held in positionby the bolts and the locking-nuts 22.

'As in common with other machines of its class, the table 4 is requiredto have in intermittent rotation and be stopped as each mold insuccession is broughtto the front, and to efiect accuracy in so placingthe molds the upper surface of the table is provided with as many holesas there are molds, and in connection with these holes there is aspring-held bar 24, adapted to slide in a suitable guide 25, bolted onthe top of the base. To release the bar 24 from a hole inthe table, itslower end is pivoted to a treadle 27, operated by the foot of thepresser-man.

29 is a bracket on the central column 2. It is split at its end to theleft in Fig. 2 and closed tightly on the column by means of bolts shownin that figure. The bracket 29 carries the pressing and blowingapparatus .and their attachments, whichwill now be de- 30 is a verticalshaft adapted to have a vertical-reciprocating movement in the project:ing end of the bracket 29, which at that point is split and fitted withbolts 0, whereby loose motion may be taken up, as shown in Fig. 1. Tothe lower end of the vertical shaft 30 is removably attached thecarrying-plate 82, having at its under face the follower 33, the lowerportion of which is reduced in diameter, so as to fit into the upper artof the the said shaft projects below the follower and forms a plungerwhich in the seeing operation first ives to the body 0 molten glass inthe mol a hollow form.

is a horizontal shaft journaled in the bracket 29, havin at each end acrank 37, and the crank to the'right in Fig. 1 has a lat- ,eralextension 39 of any appropriate shape, to which a hand-lever 40 isscrewed. A looknut serves to prevent the unscrewing of the loan -lever.v

The u per end of the vertical shaft 36 is threads and extends through aninteriorlythreaded nut 42, adapted to turn loosely in a cross-head 45.By turning the nut 42 independently of the cross-head the depth ofpenetration of the lower end of the shaft within the mold with a givenmovement of the actuating devices, as ereinafter described, may beeasily regulated.

'diately beneath it.

4:2 is a second cross-head, which is arranged sas es to slide verticallyalong but independently of 6 5 the movement of the shaft 36, and it isconnected to the carrying-plate 32 by the pair of stems 4C9.

is a coiled spring on the vertical shaft 30, extending between the twocrossheads, and its object is to give to the follower a yieldingmovement in the depression of the said shaft, and thereby effect theclosing of the moldby the follower without respect to the degree ofpenetration of the lower end of the shaft into the mold and the moltenglass therein.

. The devices whereby movement of the crank 37 is transmitted to thecross-head 45 consist of the links 52, which couple the ends of thecross-head with the crank-pins.

In order that the vertical shaft 30 with its attachments may beyieldingly held in their highest position, the lateral extension of thecrank 37 to the right in Fig. 1 is provided with a bar 53, carrying aweight 55, which overbalances the vertical shaft 30 and its attachments.

57 is a branched bracket extending fromthe central column, in the end ofwhich the airpipe is arranged to slide. The upper end of the pipe isprovided with a teat suitable for connection to a flexible tube (notshown) leading to some source of air under pressure.

The lower end of the pipe 59 is made to move longitudinally of andwithin a sleeve 60, having at its bottom a follower 62, which serves totightly close an uncovered glasscharged mold when such is brought imme-The movement of pipe 59 is communicated to the sleeve 60 by means of acoiled spring 63, the upper and lower ends of which are connected,respectively, to a collar 64, fastened to the said ipe and the top ofthe sleeve. This fiexib e connection serves to take up part of thedownward move.- ment of the pipe in excess of that required to close the11101, and at the same time effects a sufficient pressure of thefollower on the surface of the mold with which it is broughtin contactto insure non-leakage of air in the blowing operation.

The air-pipe 59 ward motion of the vertical shaft 30 and its attachmentsby means of a triangular bracket 65, attached to the stem. 49,- which isshown tothe left of Fl 15 The outer end of the bracket 65 loose y graspsthe said ipe and strikes the collar .67 on the pipe. Tliis collar whenthe shaft 30 is elevated is considerably is depressed in the down- IIObelow the'operative end-of the bracket 65,

I have stated that the upper horizontal cam-face b will limit the extentof depression sas es of the stems 9; but the said surface need not one,as the said guide-plates are vertically al-' terable in position on thebolts which sustain them.

Supposing the various parts of the machine to be in the positionsillustrated in Figs. 1 and 2 of the drawings and the presser-man to bestandin in froht of the machine, the gathering-boy olds a mass of moltenglass over the mold immediately to the right of the presserman, who clisit from the gathering-rod and allows the l beneath. The presser -manthen turns the table to the left until the charged mold is directly infront of him, when the table is automatically locked. The presser-manthen draws down the lever 40, when the vertical shaft and its follower32 descend to ether until the mold is tightly closed by the fol ower.The vertical shaft then descends alone, the

7 spring 50 being compressed in the operation,

and its end enters the glass contained in the plunger and forms a cavitytherein. The presser-man then releases the hand-lever, which rises withthe vertical shaft 30 and its follower 32,and turns the table to theleft, when the roller 17 of the lever 12 by ascending the inclinedportion a of the cam-face effects the lowering of the plunger in themold.

Before the mold reaches the secondposition the latch, which forms thebottom of the bott e or jar, is'pushed inward, so as to close the o enbottom of the mold. When the mold has reached the second position andthe tablehassto ped, asimilarpressing o eration is erformed with respectto the mo d to the rig t of the one just referred to, and at the sametime the follower 62 descends to and closes the first mold, andcompressed air being admitted to the pipe 59 the bottle or jar is blown.Before the roller 17 of the lever 12 belonging to the first mold reachesthe other or second inclined cam-face the mold is opened by an attendantandthe com leted bottle or jar taken out, the supp y of compressed airhaving been automatically stopped. The mold is then closed and the plate71. withdrawn to its original position, when the mold is ready for asecond charge of molten glass. I have described the operation of makingone bottle; but this operation is the same with each mold successively,a stop in the motion of the table being had as each mold comes to thefront of the machine and opposite the presser-man? I have not describedthe appliances whereby air is automatically admitted from the airpipe tothe mold, for the reason that such apass to fall to the locked moldpliancesare'commonly used in machines of this class and they form nopart of my invention;
